I am currently running red ribbon linux on a fat (nand) ps3, installed on a usb drive. It has a 3.12 kernel with patches (but I cannot find the source of this kernel with pathes anywhere?).

Maybe here?

You can strip that to about 7.5 MiB:

  strip -s -R .comment vmlinux -o vmlinux.strip

ps3_defconfig needs no initrd.  What is your kboot.conf?
